Snipped for focus. Reading what you wrote made me wonder if NV accidentally dropped Leon and panicked, not wanting to be blamed so instead concocted a story about a bouncer, bassinet, etc. I mentioned upthread that the reason we're hearing about him falling out of very different objects might be because it wasn't true, and she didn't remember what she told 911, therefore her story about what he fell out of has changed.
I don't know much about babies, as I didn't have any, but I babysat a few months old baby once when I was 15 or 16. I had him on top of a dresser that was his changing table. I turned away for something, not knowing how fast and squirmy babies could be, and he rolled off. Babies may be quick and squirmy but I'm quicker, thank goodness. I THANKFULLY grabbed a leg as he fell and caught him. My heart was pounding but I learned a valuable lesson.
Reflecting on that makes me wonder had I not caught him, what would I have told the mother? I'm thinking I'd likely be too embarrassed to tell the truth, that I basically was responsible for letting him fall. Especially if there was visible damage. Would I have come up with something that put the blame on the child, like it appears NV has when she said *He* fell out of his <insert your choice of options we've heard about>?
Thinking back on my own experience it's really making me wonder if it was an accident with Leon. Maybe something stupid like he wouldn't stop crying, so she was tossing him up in the air and catching him (till she accidentally didn't) hoping that would make him stop. People don't always do the smartest things. ALL MOO!
